The Almondsbury Interchange is immediately adjacent to junction 16 of the M5, which allows traffic on and off the motorway from the A38 road running between Bristol and Gloucester.

Unusually within the UK motorway system, this forces multiple lane changes for vehicles traversing some of the routes.

[5] The interchange handles high volumes of traffic especially in the morning and evening rush hours.

The more vehicles there are, the harder it is to change lane, and when in the summer season of holiday traffic, the vehicles crawl along or grind to a halt, the surrounding sliproads can simultaneously become blocked, and this can make things even more difficult on the M5 for those wanting to change lane.

Thirty-three new overhead gantries have been installed to advise motorists on the speed limits applicable at the time.
